在用Eviews操作VEC模型预测时出现以下结果：
Model: Untitled
Date: 03/02/14   Time: 23:17
Sample: 2012M11 2013M11
Solve Options:
        Dynamic-Deterministic Simulation
        Solver: Broyden
        Max iterations = 5000, Convergence = 1e-08

Parsing Analytic Jacobian:
0 derivatives kept, 0 derivatives discarded

Scenario: Baseline
Solve begin 23:17:14
Solve complete 23:17:14

Scenario: Baseline
Solve begin 23:17:14
Solve complete 23:17:14
不明白这是怎么回事？为什么没有最后的预测值或者趋势图？上面这些是什么意思？哪位同学可以帮忙解释下？
